It sounds like you have a few of the wires mixed up. I don't know what colors the factory harness uses but the white colors on most brakes controllers will be as follows: That said, you would also want to check the third brake light fuse as well.

Black = 12 Volt Power
Red = Stop Light Switch
White = Ground
Blue = Brake Output

If you want to avoid having to do any splicing we do have plug-n-play options available which will be dependent on which brake controller you are using. If it's a Tekonsha Brake Controller like the Prodigy P3 part # 90195 then you can use the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3064-P. We also have the Curt Echo Wireless Trailer Brake Controller part # C51180 which doesn't require any sort of adapter harness and you don't have to drill into the dash to install it like the above.
